Definition

A peripherally inserted central catheter (PICC) infection occurs when bacteria enters the bloodstream through or around a
central line catheter
. A
PICC
is a long, thin tube that is inserted through a vein in the arm. The catheter is threaded through the arm vein until it reaches a larger vein close to the heart. Commonly called a PICC line, it is used to deliver medication, nutrition, IV fluids, and
chemotherapy
.

If bacteria start to grow on the
central line catheter
, they can easily enter the blood and cause a serious infection. This can lead to a condition called
sepsis
, which occurs when bacteria overwhelm the body.

Causes

Bacteria normally live on the skin. Since the catheter is inserted through your skin, these bacteria will sometimes track along the outside of the catheter. From the catheter, they can get into your bloodstream.

Risk Factors

Factors that increase your chances of developing this infection include:

Having a catheter for a long time

Having a catheter that is not coated with a substance that kills bacteria

Having a catheter inserted into a vein in the thigh

Having a weakened immune system

Being in the intensive care unit

Having an infection elsewhere in the body or skin

Symptoms

Symptoms may include:

Fever

Shaking, chills

Fast heart rate

Redness, swelling, or tenderness at the catheter site

Drainage from the catheter site

Diagnosis

Your doctor will ask about your symptoms and medical history. A physical exam will be done.

Your bodily fluids may be tested. This can be done with:

Blood tests

Cultures

Images may be taken of your heart. This can be done with
echocardiogram
.

Treatment

Talk with your doctor about the best treatment plan for you. Treatment options include the following:

Antibiotics—Antibiotics are medications used to treat an infection. The kind of antibiotic you will be given depends on which bacteria is found in your blood.

Central line care—Often, the PICC line will need to be removed and replaced by a new catheter.

Prevention

At the Hospital

When you are getting a PICC line placed, the staff will take steps to reduce your risk of infection.

There are also steps that you can take to reduce your risk of infection:

Ask the staff to take every precaution to prevent an infection.

Tell the staff right away if the bandage needs to be changed or if the site is red or sore.
